The Viking Arm Decking Kit DK2 makes decking installation easier, precise and hassle-free. If youve already got the Viking Arm tools, and you want to put down some decking with ease, then this is the kit you need. You can use your Viking Arms to level, press, squeeze the foundation into place. The decking kit includes shaft extenders, and 4mm spacers to ensure that your deck is perfectly spaced and placed before screwing it to the frame. You can press several boards together at the same time as well as straightening warped boards as well as being able to fasten them all before moving on to the next row.
